No NAND access on AT91SAM9G20-EK

[Mickael Chazaux]

Hi,

I managed to compile Barebox for AT91SAM9G20-EK, and I can run it. However
it seems not capable of reading the NAND Flash.

Output is at [1], my configuration is [2]. The "err -74" is EBADMSG, in
line 1057 of "file drivers/mtd/nand/nand_base.c"
